The "coming of the Kingdom" is an historical process unfolding in a physical world.

One of the distinguishing features of modernity has been the universal awakening of historical consciousness. An outcome of this revolutionary change in perspective that greatly enhances the teaching of Bahá’u’lláh’s message is the ability of people, given the chance, to recognize that the whole body of humanity’s sacred texts places the drama of salvation itself squarely in the context of history. Beneath the surface language of symbol and metaphor, religion, as the scriptures reveal it, operates not through the arbitrary dictates of magic but as a process of fulfilment unfolding in a physical world created by God for that purpose.
